What factor most influences knot security in intracorporeal suturing?

• A. Adequate needle passage, proper tissue capture, and appropriate tension.
• B. Suture color and length.
• C. Camera brand and setup.
• D. Surgeon's height.

Answer: (A)

Knot security in intracorporeal suturing hinges on technique that controls how the suture engages tissue and is tightened. Adequate needle passage ensures the suture enters and exits with proper bite size and angle, so the limbs load evenly and don’t cause tissue tearing or uneven tension. Proper tissue capture means grabbing enough tissue so the knot can grip effectively and resist slippage; too small bites weaken the hold, while overly large bites can injure tissue and disrupt knot integrity. Appropriate tension then cinches the knot snugly against the tissue without over-stressing the suture or causing tissue damage; too loose and the knot can loosen, too tight and tissue or suture can fail. Color or length of the suture, camera brand or setup, and the surgeon’s height don’t influence the mechanical security of the knot in the same way. They don’t change how the knot resists loosening once the needle path, tissue capture, and tension are controlled. Mastery comes from consistently applying the right needle passage, grabbing the right amount of tissue, and applying the correct tension on each throw.
